How to apply a "Heat Flux" boundary condition on a vertex in ANSYS Workbench
 

I want to solve in Workbench a 1D problem of heat conduction. In the same way that I am able to apply a "Force" boundary condition on a vertex in the structural analysis, I want to apply a "Heat Flux" on a vertex in the thermal analysis (the equivalent to a force in the structural study), but I cannot do it from the "Mechanical" application. I am only able to impose a "Temperature" or "Heat Flow" boundary condition on a vertex. Any clue about it? Isn't it possible to solve a 1D problem of thermal analysis as I can do it for the structural part?

My geometry is composed of lines that have assigned a circular cross-section.

Solved it. In this case it's just applying a "Heat Flow" boundary condition (imposing a heat source) on a vertex, whose value is computed from the definition: Heat Flux = Q/A, where A is the cross-sectional area of the truss and Q is the heat source.
